Heving Ehe ebove end other objects in view, es Will hereinefter more fully eppeer, Ehe invenEion consisEs in Ehe novel constsruction, oornbinetion, end errengernent; of perts hereinefter described end cleirned.

1 heveillustreted m y invention in Ehe ecoompenying drewings, wherein- Figure 1 is e side elevetion, perEly in section, 01' my irnproved brece wiEh e breestpiece of cirouler contour epplied Ehereto. Fig. 2 is e verticel seotionel view of Ehe upper end of Ehe brece end of pert of Ehe breest-piece shown in Fig. 1. Fi,q. 3 is e side elevetion, perEly in section, of e preferred forrn of breesE-pieoe edepted Eo be epplied Eo Ehe b1eoe shown in Fi,q. 1. Fig. 4 is e side elevetion of e seotionel biE edepted Eo be used in connecEion WiEh Ehe breoe shown in Fig. l.

The shenk 1 of Ehe breoe is of-Ehe usuel shepe, boing e round seotion of metel bent Ewioe et 1'ight engles so es Eo forrn e orenk, end Ehe c1enk portion of Ehe shenk between Ehe bends is formed WiEh two ennuler grooves 2 end 3. A handle 4, which is fitted onEo Ehe shenk he- 'lol'e Ehe bends e1e medein Ehe seine, is formed with e centrel opening '101 Ehe pessege of Ehe shenk end WiEh ennule1 grooves 5 end 6 in its inner wells, seid grooves coinciding WiEh Ehe grooves 2 3 in Ehe shenk. Bells 7 8 ere errenged in Ehe weys whioh ere formed loy Ehe co1ncid1ng grooves in Ehe shenk end 1n Ehe hendle, Ehe seid bells be1ng puE1nto Ehe weys Ehiough holes 10 11 in Ehe handle, Ehet; efter Ehe bells beve been introduoed ere closed by sorew-plugs 12 13. The upper end o1 Ehe shenk is cone-sheped, es shown in Fig'. 2, end formed WiEh en ennuler groove 14, EheE receives e Ehumb-sorew 15 in Ehe sleeve 16, whioh sleeve is fitted over Ehe upper end of Ehe shenk end oerries Ehe knob 17, egeinsb which Ehe person usin,q Ehe hrece presses Eheir hend 01 body. A screw 18 is seE in Ehe sleeve 15 end oerries e hell 19, which is sooketed in e suiE- eble oevity in Ehe end of e sorew 18 end beers egeinst Ehe end 0f Ehe shenk, so es Eo efford en enEifriouion-beering et Ehet poinE.

The breesE-piece shown in Fig. 3 of Ehe drewings, whioh is Ehe fornn of breesbpiece Ehet I prefer Eo employ, is composed of Ehe sleeve 16, Whieh corresponds in ell perticulers Eo Ehe seine pert of Ehe breest-pieoe shown in Fig. 2; buE in Ehis cese 1 subsbitute for Ehe knob 17 e curved bei 20, end upon seid her 20 1 mounE e curved meEellic breestplete 21, Ehe seid breestplete being secured in position upon Ehe fece of Ehe bei 20 by bolns 22 22, which pess Eh1ough Ehe eurved bei 20, spirel springs 23 23, whioh ere sooketed in holes 241 2& in Ehe her 20, surrounding Ehe sorews end serving Eo meintein Ehe breestplete 21 resilienEly et; e shortdistence from Ehe bei 20. The lower end of Ehe brece oer1ies e ohuok 25, Ehe seid ohuck being formed With e screw-Ehreeded oevity in iEs uppor end Ehet receives Ehe sorew- Ehreeded lower end 26 of Ehe brece, Ehe chuck when in position beering egeinst e shoulde1 27 end being secured in position by 1neens of e sliding pin 28. 'lhe pin 28 pesses Ehrough Ehe shoulder 27 end when Ehe ol1ucl; is sorewed home 011 Ehe shenk enters e hole in Ehe ohuck end holde iE egeinst roEery n1ovoment. A smell spirel spring surrounds Ehe pin 28 end serves Eo impel it into Ehe hole in Ehe ohuok. The ohuck 25 is provided wiEh Ehe moveble jews 29 29, whioh ere edjusted in Ehe ordinery menner by e screw-ring 30.

The brece, es shown in Fig. 1, when litted WiEh either Ehe breoe-knob shown in EheE figure 01 W1'll Ehe breesE-piece shown in Fig. 3, is edepted Eo be used in Ehe menne1 of enyordinery brece, such es Ehe bveoe cornmonly used loy cerpenters o1 meohinists for holding eugers, d1ills, end Ehe like.

In Fig. 1 0'f Ehe drewings I heve illustreted e seotionel coel-drill edepted Eo be used by miners in connection wiEh Ehe perEs shown in Fig. 1, Ehe seid drill being co1nposed of Ehe biE 38, which hes e shenk 39, EheE is formed with a serew-Ehreaded cavity 4:0 adapted Eo receive Ehe screw-Ehreaded end 26 of Ehe brace 01' when iE is desired Eo lengEhen Ehe drlll E0 receive Ehe screw-Ehreaded end 41 0f an ex- Eension-piece 42, which has on iEs 0Eher end a serew-Ehreaded hole &3 EhaE is also adapted Eo reeeive Ehe screw-Ehreaded end 26 of Ehe brace.

IVhile my improved brace is adapted Eo be used in Ehe same manner and for Ehe same purpose as ordinary braces, in which event Ehe knob 17 and ehuel 25 rnay be arranged on Ehe brace as shown in Fig'. l, I prefer Eo ernploy in eonneeEion WiEh n1y improved brace Ehe miners boring-Eool, (shown in Fig. 4,) and I also prefer Eo employ Ehe breasE-pieee shown in Fig. 3, as Ehe boring 0'f h0les in coal en- Eails Ehe exertion 0f considerable pressure on Ehe breasE-piece 0f Ehe braee, and in braces of Ehe ordinary charaeter Ehis pressure is very difiticult E0 maintain, owlng Eo Ehe shocks and vibraEions EhaE are eonveyed Eo Ehe person using Ehe brace Ehrough Ehe breasE-piece.

I/ViEh my improvemenEs Ehe spring-sus- Eained breastplaEe 21 entirely obviates Ehe eommunicaEion 0f vibrations and ja1ring m0- Eions Eo Ehe person using Ehe drill.

'Ihe improved handle above described WiEh Ehese ball-bearings constiEutes an important adjunet 01 my brace, as iE alrnosE entirely 0bviates any fricEion between Ehe handle and Ehe crank porEion 0f Ehe brace and renders Ehe Same very mach easier Eo operate Ehan where handles 0f Ehe ordinary characte1 are employed.

Having deseribed n1y invention, I elai1n 1. The cornbinaEion in a brace, of an angula1 one-pieee shank and a handle consisting 0f a single section 0f material, Ehe said handle having annular grooves in iEs inner Wall, h0les openinginEo said grooves, halle located in said grooves and rneans f01 closing Ehe holes afer Ehe halle are inErodueed and Ehe said shank having grooves corresponding Eo Ehe grooves in Ehe handle.

2. In abraee,ashank havinga serew-Ehreaded end and a shoulder adjacenE said end, said end being adapted Eo receive a ehuck having a serew-Ehreaded Socket WiEh a spring-pressed pin passing Ehrough Ehe shoulder and adapEed Eo engage Ehe chuek.

3. In a braee, Ehe eornbinaEion wiEh a onepiece shai1k, having a cranked portion, 0f a one-piece handle mounted on said eranked por- Eion and revoluble Ehereon, and susEained againsE longitudinal movennenE by grooves in Ehe shank, corresponding grooves in Ehe handle and interposed halle.

4. In a brace, a shank having a erank por- Eion formed exclnsively by bending Ehe shank and of even diameter between Ehe bends, said crank portion being provided WiEh a plnrality 0f eireumferenEial grooves, in eombination WiEh a handle consisting 0E' a single pieee of n1etal piereed f01' Ehe passage 0f Ehe shank and provided \ViEh grooves in iEs b0re, located wholly inside Ehe ende of Ehe handle and spaced apart a distanee equal Eo Ehe spacing of Ehe grooves in Ehe shank and halle loeated in Ehe ways f0rrned loy Ehe eoineiding grooves in Ehe shank and handle.

5. In a brace, Ehe combinatsion WiEh a shank having a shoulder near iEs end and a screw- Ehread exteriorly 01 Ehe shoulder, a pin passing Ehrough Ehe shoulder, a spi1al springsurrounding said pin and impelling Ehe pin Ehrough Ehe shoulder, 0f a chuck having a serew-Ehreaded eavity in iEs end, Eo receive Ehe Ehreaded end of Ehe shank and a hole adjacent said caviEy Eo reeeive said pin.

6. In a hrace, Ehe cornbination 0f a shank, a sleeve revolubly mounEed on Ehe shank, rneans f01' maintaining Ehe sleeve 011 Ehe shank. a eurved bar carried by said sleeve, a curved metallie breastplate, holte having nuEs coun- Eersnnk in sa'1d breasEplate and heads disposed 0n Ehe outerside of said bar, and spiral springe interposed beEween Ehe breasEplate and said bar and seated in recesses in said bar.
